The Application of XRF in Field Monitoring on Digging Pb-Contaminated Soil
In this paper, a portable X-ray fluorescence (XRF) is designed to monitor the digging process of Pb contaminated soil based on contaminated site remediation. This field monitoring method is applied to the project of Pb contaminated restoration site K. A full time program is designed for XRF to monitor the exceeded standard regions of Pb pollution during the digging contaminated soil. The acceptance monitoring results show that the Pb concentration of all original exceeded points are under the limit value 260mg/kg, and reach the requirement of environmental protection. This application results show that the portable XRF was designed effectively in field monitoring on heavy metal such as Pb, which realize the purpose of quickly identification and digging of contaminated soil.
